Be it lrnown that l, FRED C. CLARKE, a citizen of the United States, residing at lllinlield, Cowley County, Kansas, have invented a certain new and useful .improvement in Stack (lovers, oit which thefollowing is a full, clear, and exact description,

'j such as will venable others skilled in the art ytion being to provide a simple and eiiicient cover in the nature of tarpaulin of suiiicient size to cover the entire upper portion ot a relatively large stack of hay, grain, or the likeg'to provide simple means forsupporting and handling said cover while `the same is being` applied to or removed from position upon a stack, and further to provide simple and efiicient means for spreading the cover and retaining it in position upon the stack.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement ot parts hereinafter'more fully described and claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevational view of a stack cover or my improved construction, the same being shown in position on a stack.

Fig. 2 is an end elevational view of th cover applied for use. f

Fig. 3 is a plan view of one of the spreadkers made use of in carrying out my invention. j j

Fig. 4 is a plan view of one ot the rings that carries the cover supporting rope or cable. n f- Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10, 10 designate posts or uprights that are spaced a suitable distance apart, with their base portions embedded in the ground. ln order toL main tain these posts iirmly in position, I prefer v to set their lower ends in blocks of concrete 11, andto brace them by means of guy wires or cables `12, which extend from the upper ends oi the posts to suitable anchors 13, the latter being embedded in the groundv at wiirrnnn, Kansas.

points laterally disposed with respect to said posts. f

Rings lll? are arranged to slide freely upon the posts or uprights 10, and secured in any suitable manner to either one oitliese rings is one end of a stout rope or cable 15 that serves as a supporting member or ridge for the cover 16. The opposite end ofthe rope or cable is connected to the end or" a short cable 1'? that passes varound a pulley block 18, preferably oi' the selidoclring type, and this pulley block is secured in any suitable manner to the adjacent one of the rings 14.

The' cover 16 is formed preferably ci? vcanvas on analogous material that may be water-prooted, it desired, and it .rests on the rope or cable so that substantially equal parts are positioned on opposite sides thereof. This cover may besecured to the rope or cable in any suitable manner, and arrangedv adjacent to its lower edges are suitable openings in which are located eyelets 19. Secured in any ysuitable manner to the rings 14- are the ends of ropes or cables such as 20, and the vupper portions thereof pass over pulleys 21, which latter are secured in any suitable manner to the upper portions of posts 10. The lower portions of these ropes .or cables 20 are adapted to be secured to cleats or similar brackets 22 that are secured to the lower portions of posts 10.

Arranged to slide freely upon the posts 10 below the rings 14 are spreaders for the ends of the cover 15, said spreaders each comprisinga ring to which is secured a substantially straight bar 24,-, the ends of which terminate in pins 25 that are adapted to engage with the eyelets that are immediately adj acent to the ends of the cover, and, consequently, holding the ends of said cover in position beyond the ends of the stack when saidcover is positioned thereupon. To hold these spreaders-irmly in position, guy ropes, such as 26, are extended from the ends of said spreaders downward to the anchors for the guy wires or cables 12.

When my improved stack cover is in use it occupiesa position over the upper portion of a stack of hay, straw, grain, or the like, as illustrated in Figs. l and 2, and said cover is iirmly held in such position by the rope or cable 15, and which latter is drawn taut between the upper portions of the posts 10 by proper manipulation of cable 17 upon the self-locking pulley '18. The cover 16 is raised or lowered byproper manipulation of the ropes 20, and a'iter the position ot the cover has been adjusted, said ropes 20 are secured in the usual manner to the cleats Bitter the ends oiz the spreaders have been properly connected to the corners or the cover and the guy ropes 26 secured to said spreaders, the lower edges of the cover are anchored to the body el the stach by means ot suitable pins? such as 27, that are inserted through the eyelets 19. (See Fig. 2.)'

A stack cover of my improved construction is comparatively simple7 is capable of being readily `manipulated While being placed in position upon or removed from a stack, and` in addition to serving as a protective covering tor staclzs of hay, grain, or the like, can be utilized as a temporary coverin` for farm machinery7 large vehicles, and the like. t

It will be readily understood that minor changes in the size,L form and construction of the various parte of my improved stack cover can be made and substituted ior those herein shown and described Without departscope or which is set forth in the appended claims.

l claiml. The combination with a pair of uprights, of members mounted for vertical adjustment upon said uprights, a flexible member connected to said vertically adjustable members, means for drawing said flexible member taut5 a cover carried by said flexible member and spreaders arranged for slidingim'wement upon said uprights below the vertically adjustable members, the ends ol which spreaders the corners of said cover. y

2 rllhe combination with a pair of upfrio'htah oit a vertically adjustable member supported by said uprights? a cover carried by said vertically adjustable member, spreaders between the ends oi said cover and said uprights and f guys anchored at their lower ends and connected to the ends of said spreaders. t
